BATTERY CONSIDERATIONS

When considering a power solution for a design, the battery needs to be carefully

selected. Alkaline batteries are a commonly available option that delivers good

performance in a variety of applications. Energizer® Ultimate Lithium batteries are an

alternative power solution that provide superior-performance high drains and allows

designers to utilize the full power range of the MCP1663 without sacrificing size or

runtime.

Energizer Ultimate Lithium batteries utilize a primary cell chemistry that contain higher

energy than alkaline batteries, and have much better high drain performance. Ultimate

Lithium batteries produce a high, flat voltage profile that enables them to provide a high

energy capacity even at high drains. Additionally, Ultimate Lithium batteries have a very

low internal resistance, allowing them to maintain a high voltage at very high loads.
